[SOLVED] question about microcontroller LM3S9C97

Hi all

I have i am a new to circuit designing. I have two question what does this means

1. "which hardware is needed for programming the LM3S9C97 (programming and debug interface)"

2. which software/IDE can be used to develop the firmware for it?

My suggestion would be to go for the Keil programming IDE. They also suggest a few good JTAG debug and programming devices.

By the way wat do u mean by "whichhardware is needed for programming" does this mean i need have another hardware to just do programming.

If you have a board with that processor on (or almost any other uC), you will need separate hardware like a JTAG or ISP programmer to download your code to the uC or flashmem or to debug your programming.
Something like this for example:
https://www.segger.com/jlink.html

You can also get a development / evaluation board which already contains a bootloader downloaded to the board using a device like the one above.
Then the bootloader will will enable you to download your program onto the board through for example: a serial port.
See some examples of such boards:

okay.

what if I make my own PCB design then I would need only JTAG or ISP programmer right?

Also which software/IDE can be used to develop the firmware for it?

Is that KEIL we use to develop the firmware?

Yes, if you design your own board you would only need a JTAG or ISP programmer.

Keil is only one of the software IDEs that can be used to develop the firmware for your board. There are quite a few on the market:
www.keil.com
www.rowley.co.uk
www.iar.com

or the GNU tools:
www.gnuarm.com

While the LM3S9C97 does have a ROM based bootloader, to do serious development, you'll need a JTAG programmer/debugger, two of most popular being:

Segger J-Link



Segger offers a noncommercial/educational J-Link, at a fraction of what the commercial version costs:

Segger J-Link EDU

There are, of course, clones and inexpensive alternatives, however at the price of the J-Link EDU, why bother?


KEIL's MDK-ARM is probably the most used IDE/Compiler suite, you can freely download the MDK-lite version which has only has the limitation of 32kB maximum code size.

Thanx Bro really appreciated.

Just one last question do u know any tutorial websites for me to learn?

There are not many ARM tutorials on the NET.

I can highly recommend the Valvano series of texts which use the TI/Stellaris series of ARMs (LM3Sxxx):

Embedded Systems: Introduction to Arm Cortex-M3 Microcontrollers

Embedded Systems: Real-Time Interfacing to the Arm Cortex-M3

Embedded Systems: Real-Time Operating Systems for the Arm Cortex-M3

I've recently read all three volumes and they are quite good, I've list them in their suggested order of reading above.

I should also mention the KEIL MDK-ARM has an extensive collection of example code and a relatively good online help system.

Thanx "Bigdog" and "notamoderator"

REALLY APPRECIATED.

I did come across these informative tutorials on the use of CMSIS (Cortex Microcontroller Software Interface Standard).

CMSIS provides a common programming interface and library routines for all ARM Cortex-Mx devices regardless of the manufacturer.

The TI/Stellaris LM3Sxxx series is a ARM Cortex-M3 device and therefore can utilized CMSIS.

And the following ARM tutorials, although based on the STM32 series of devices and the GCC toolchain:

Just one last question.

My friend wrote the code for MSP430F2416 and can I also use the same code in LM3S9C97?

They are both from Texas Instrument.

You maybe able to port some C code or routines to the LM3S9C97, however the ARM Cortex-M3 and the MSP430 are two entirely different MCUs.

So the quick answer would be, the code is not directly compatible.


BigDog

Even though there are from the same manufacturer?

Yes, even though they are not from the same manufacturer.

The MSP430F2416 is a 16-bit RISC CPU with two built-in 16-bit timers, a fast 12-bit A/D converter, a comparator, four universal serial communication interface (USCI) modules and up to 64 I/O pins.

Typical applications include sensor systems, industrial control applications, hand-held meters, etc.

I can with confidence state, that they are two completely different animals.

Hw abt i use TMS320F28069 instead of LM3S9C97?

Or you could rather go for the Intel BV80605001911AQ paired with the BD3450 chip for interfacing??
That would be much more scalable.
